Generally speaking the metals have an easy time releasing one or more electrons (low ionization energy) giving them a positive charge.
Many non-metals have room in their outer orbitals to accept these electrons (high electronegativity), so they take on a negative charge.

because of the number of electrons in the outer shell. Ionic compounds generally form because the atoms want to achieve a stable state of the electron configuration. This means that if you only have one or two of the eight electrons needed to fill your outer shell, it's easier just to lose them to say... an atom that is lacking one or two electrons. So to complete as many shells as possible, electrons tend to leave metals, especially of the first two groups, creating a positive ion; and those electrons can then complete the outer shells of other atoms, especially the halogens which lack but one electron and having gained an electron they become negative ions.

Not all metal compounds involve ions. Organometallic compounds have what might be called a polar covalent bond between carbon and a metal. Simple rules only work for simple things and chemistry is not simple.

hey, not all nonmetals consists of ions, this depends on the elements that the compound consists of

one looses an electron and one gains an electron ex. NaCl . one becomes a cation and the other becomes a anion.
